What is the range of sand size in terms of diameter?

• A. 1.0 mm to 0.1 mm
• B. 3.0 mm to 0.25 mm
• C. 2.0 mm to 0.050 mm
• D. 5.0 mm to 0.001 mm

Answer: (C)

The range of sand size is defined according to the Wentworth scale of grain sizes, which specifies sand as having a diameter between 0.0625 mm and 2.0 mm. The correct answer indicates a range that captures the upper limit of sand size effectively. In this case, the range given in the answer reflects common terminology in materials science. Sand is often classified to include particles that are between 0.0625 mm and 2.0 mm in diameter. The choice indicating a size range between 2.0 mm to 0.050 mm aligns with common misconceptions, as it seems to misrepresent the actual definitions of sand size. Specifically, anything larger than 2.0 mm is typically classified as gravel rather than sand, while anything smaller than 0.0625 mm is classified as silt or clay. Thus, the correct choice reinforces the industry-standard terminology used in various fields such as civil engineering, geology, and materials science when referring to particle sizes within the sand classification. Understanding this classification is crucial for applications where the size of particulate materials directly impacts the behavior of materials in construction and other engineering applications.
